The symbol π was introduced by the mathmatical
William Jones in 1706 his symbol was adapted by
Euler in 1737 who wrote 3.14159=π Tand became
the standard symbol of π- Molly
Fomrulas
There are several diiferent formulas fo pi. Here are some: The diameter time pi equals the circumference of a circle. C = Dπ The radius times pi squared equals the area of a circle. A = Rπ2 - Ethan
Guess What
1. Guess what, in September 2002, Dr. Kanda of the University of Tokoyo calculated 1.2411 trillion digits of pi.
2. Guess what, there's a more accurate fraction of pi. It's 104348 / 33215 which is accurate down to 0.00000001056%.
3. Guess what, Hiroyoki Gotu memorized 42,000 digits of pi. 4 The real number for Pi has never been found. It's otherwize known as googol-plex. 5.Check out cool PI poems here. Also, check out this cool link. It can find stings of numbers for the first 200,000,000 digits of pi.
Cacutating π
π can be calculated by drawing a large circle,
then measuring its diameter and circumference
and dividing the circumference by the diameter
(or circumfrance is about the size of 3x the diameter).-Molly
EXAMPLE QUESTION:
Below there is a pizza, thediameter of the pizza is 9.65

What is the circumfrance?
Now, about what is the circumfrance?
